I also upgrade the XULRunner in update site files. The version for Linux 64bit is based on the last night build. Since Mozilla has stop the support of 1.9.2.x / 3.6.x, these files maybe is the last version that support JavaXPCOM...

Please let me know if these files does not work in your enviorment. Thank you.

If a custom tag will generate several HTML elements, the setMappingAttribute(attributeName) API could let each element mapping to different attribute. So
For example: <t:inputText label="Name" value="Bravo Editor"/>
will generate:<div><span>Name</span><input type="text" value="Bravo Editor" /></div>

When you click text inside <span>, the cursor of source editor will move to attribute 'label'.
When you click <input>, the cursor of source editor will move to attribute 'value'.
